Abstract

PURPOSE:To effectively utilize the heat generated by a heater and to increase the gas temperature, by positioning a gas feeding pipe to lead a fuel gas and an oxidizer gas close to the inner periphery of a fuel cell housing tank. CONSTITUTION:Manifolds 2 which consist of a pair of a fuel gas pipe and an oxidizer gas (mainly of oxygen contained in the air) pipe are furnished at both sides of a cell main body 4, a gas feeding pipe 3 to lead the gas to the manifolds 2 is installed, and a fuel cell housing tank 1 to house the manifolds 2 and the pipe 3, and a heater 5 furnished around the tank 1, are arranged to heat the fuel cell. By arranging the gas feeding pipe 3 close to or in contact with the inner periphery of the fuel cell housing tank 1 in such a way, the heat generated by the heater 5 can be utilized most effectively.

In the figure, the fuel cell has fuel gas on both sides of the battery body 4,
It is equipped with a pair of manifolds 2 each for oxidizing gas (mainly oxygen contained in air), and is composed of gas supply pipes 3 that lead gas to the manifolds 2, and a fuel cell storage tank 1 that houses these and its outer periphery. A heater 5 provided in the fuel cell is provided for heating the fuel cell. Generally, the power generation characteristics of a fuel cell are highly temperature dependent, and the higher the operating temperature, the higher the generated voltage. For this reason, it is necessary to raise the temperature of the fuel gas and oxidant gas that contribute to power generation in advance so as not to lower the operating temperature.
